ANTHRAQUINONE DERIVATIVE AND PROCESS OF MAKING SAME.

SPECIFICATION forming part of Letters Patent No. 617,981, dated January 17, 1899.

Application filed December 27, 1897. Serial No. 663,723. (Specimens) I TO all wit m1, it may concern.-

Be it known that l, OSCAR BALLY, doctor of philosophy, a citizen of the Swiss Republic, residing atjlannh'eim, in the Grand Duchy of Baden and Empire of Germany, have invented new and useful Improvements in the Manufacture of New Coloring Matters for Animal Fiber, of which the following is a.

specification.

In the manufacture of the anthracene blues a nitro -anthraquinone or reduction product therefrom, which I hereinafter designate by the collective term nitroanthraquinone body, is treated-with fuming snlfuricacid with or without the presence of a reducing bath very well and give violet to blue shades of great brightness, while the initial material .before condensation with a phenolicbody' under similar circumstances only givesbrownred to bordeaux-red shades. If the goods dyed with the new coloring-matters without a mordant be subsequently treated with chrome,

greenish-blue to bluish-green shades are ob-' gallic acid.

esters with sulfuric or 'boracic acid. It is therefore advantageous to add the phenolic substance chosen to the reaction mixture obtained by the treatment of the dinitro-anthraquinone with fuming sulfuric acid in the presracic acid. The mixture with the phenolic substance is then heated to say about sixty to eighty degrees centigrade for several hours or as long'as may be necessary in each case.

The following examplewill serve to illustrate the manner in which my invention can parts are by weight:

hundred (100) parts of fuming sulfuric acid and one and'a half (1%) parts of finely-divided sulfur. The fuming sulfuric acid may. contain, for instance, twelve (12) or forty (40) percent. free anhydrid'. Heat the mixture than about one hundred and thirty degrees centigrade,(1 30 G.) Then the coloringmatter is practically completely soluble in waway.

In the dry state the new coloring-matter is ablack powder readily soluble in Water. Instead of gallic acid other phenols or sulfophenols or carboxyphenols-or their derivatives can be used.

In the following table the properties of some of the new coloringmatters are stated:

ence of a reducing agent or of this and of bo-' best be carried into practical effect. The

moderately for several hours, but not higher Example: Mix about ten (10) parts of 1.5 dinitro-anthraqninone with fifty (50).to one ter, allow the me t to cool and add at the orwith common salt, and collect in the usual 34 Color. gi Sl t" o ttl Phenolic body em lo ed.

The temperatures, the proportions of the phenolic bodies used, strength of fuming acid, &c., can be varied considerably. Also instead of pure 1. 5 dinitro-anthraquinone crude dinitroanthraquinone, such as is obtained by nitrating anthraquinonc, can be used.

' What I claim as new, and desire to secure by Letters Patent, is

l. The process for the production of new coloring-matters by condensing sulfuric acid esters of a polyoxyanthraqninone sulfo-acid, which can be obtained by the treatment of a nitro-anthraquinone substance, as hereinbefore. defined with fuming sulfuric acid, with a phenolic substance as hereinbefore defined, all substantially as hereinbefore described.

. .3. As anewartiole of manufacture, the coloring-matteiwhich can be obtained substan tiall y as described from a nitro-anthraquinonc substance, and which dissolves in water, giv ing a violet to blue color; dyes uninordantcd Wool violet to blue shades, which on subscquenttreatmcnt with chrome become greenish blue to blue; With caustic soda the color ing-rnatter gives green to blue and with carbonate of soda it gives greenish blue to blue all substantially as described.

As a new article of manufacture the coloring-matter which can be obtained by (10111 bining the product, resulting bythe action of fuming sulfuric acid of forty per cent. SO, on

1.5 dinitro-anthraquinone, with gallic acid as hereinbcfore defined and Which is a black powder, soluble in Water with a blue color, by addition of caustic soda it becomes green; concentrated sulfuric acid dissolves it with an olive-green color, all substantially as hereinbefore described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
